Designed for wet environments
Vacuum potting helps eliminate voids around the windings and lead joints, reducing paths for moisture and condensation to reach the motor.

OUTDOOR COOLING APPLICATIONS
IP68 waterproof fan motors for equipment exposed to the elements.
A vacuum-potted motor design for cooling equipment that faces rain, dust, salt air, condensation and repeated temperature changes.
A selected configuration with the potted motor protected inside the completed fan assembly.
IP68 RANGE
Outdoor-duty motor protection across compact and larger axial fan formats.
Examples from our IP68 motor development work, showing protected motor assemblies and finished axial-fan configurations across the range.
Ingress-protection coverage, dimensions, electrical options and test requirements are confirmed for the selected model and finished equipment.
Heat has a way out
The high-thermal-conductivity compound is selected to move heat from the windings through the motor structure and into the airflow.
Built for field exposure
The cured encapsulation supports the winding structure against vibration, shock and abrasive outdoor conditions.
THE PROBLEM
Why a standard motor struggles outdoors.
A conventional fan motor relies on varnish, seals and a controlled indoor environment. In outdoor cabinets and equipment, moisture, salt fog, dust and vibration can affect winding insulation, solder joints and bearings.
For applications where field replacement is costly, the motor needs protection that begins inside the fan rather than at the enclosure door.
From exposed winding to sealed assembly
The process begins with a wound stator. In the vacuum chamber, epoxy reaches the spaces between wires, around laminations and over lead joints. After curing, the motor becomes a solid encapsulated unit intended to resist water and dust ingress for the selected configuration.

THE PROCESS
How the IP68 motor design is made.
1. Vacuum potting
The stator is submerged in a formulated epoxy compound and placed under vacuum to draw out trapped air.
2. Controlled curing
After degassing, the compound cures into a hard, sealed structure around the winding and connection areas.
3. Assembly and checks
The journal process includes run-in testing, insulation-resistance checks and final water-test verification before release.
IN THE FIELD
Applications that benefit from a sealed motor design.
Outdoor telecom cabinets
Coastal deployments, monsoon rain, salt spray and daily temperature swings.
Solar inverters and EV charging equipment
Unattended electrical equipment exposed to sun, rain and changing ambient conditions.
Greenhouses and aquaculture
High humidity, corrosive air and continuously operating ventilation systems.
Outdoor LED and cleaning vehicles
Wash-down exposure, vibration and compact enclosure cooling requirements.
Marine and port equipment
Salt-laden air and demanding service environments near the coast.
Custom outdoor enclosures
Cooling projects that need a configuration reviewed against real operating conditions.
ENGINEERING REVIEW
Specify the environment before choosing the fan.
Send the enclosure size, supply voltage, airflow target, ambient temperature range, exposure to water or salt, expected operating hours and project quantity. Our team can review the appropriate motor design and configuration.
